Diagnosis

This species can be distinguished from other species in the genus by the pronotum without tubercles; centre of pronotum sculptured, with longitudinal depression; elytra shiny, unicolorous; apex of elytra bispinose, with short spines.

Description

Female. Integument dark reddish brown; antennae and legs slightly lighter.

Head. Frons coarsely, densely, shallowly punctate; with short, sparse, gold setae, and longer setae along frontoclypeal suture. Vertex coarsely, abundantly punctate, with short, sparse, gold setae. Antennal tubercles slightly elevated, rounded at apex. Median groove distinct from near midlength of frons to posterior level of antennal tubercles. Gulamentum microsculptured, with long and short, gold setae. Mandibles with long, sparse setae on outer surface. Distance between upper eye lobes 4.6 times width of one upper eye lobe. Antennae not reaching elytral apex. Scape coarsely, densely, shallowly punctate throughout; with short and long, sparse, yellow setae. Antennal formula (ratio) based on length of antennomere III (only the holotype measured): scape = 0.68; pedicel = 0.18; IV = 0.95; V = 0.88; VI = 0.78; VII = 0.75; VIII = 0.60; IX = 0.63; X = 0.53; XI = 0.70.

Thorax. Prothorax distinctly longer than wide; distinctly constricted at posterior one-fifth. Pronotum coarsely alveolate, except anterior and posterior margin and longitudinal median sulcus in posterior half; with both short and slightly longer, sparse, yellow setae except on median sulcus. Anterior half of prosternum microsculptured and finely transversely striate; with short, sparse setae. Posterior half of prosternum coarsely, densely, confluently punctate; with short, sparse setae. Prosternal process narrowed at midlength, expanded laterally at apex, width at narrowest point equal to 1/3 of procoxal cavity width. Mesoventrite coarsely, densely, shallowly, confluently punctate laterally, sparser centrally; with short, gold setae. Mesoventral process with sides parallel, slightly narrower than mesocoxal cavities, deeply emarginate at apex. Metepisterna with dense short setae. Metaventrite with short, sparse setae laterally on anterior half, and with sparse long setae centrally; coarsely, shallowly punctate near mesocoxal cavities, with sparse fine punctures on remaining surface, except for smooth central area. Scutellum rounded at apex. Elytra coarsely, deeply, moderately punctate on basal half, gradually more finely punctate towards apex; with sparse, long setae arranged in five longitudinal rows; apex emarginate, with two spines, subequal in length, slightly longer than pedicel. Legs with femoral peduncle longitudinally sulcate. Tibiae distinctly carinate.

Abdomen. Ventrites microsculptured, mainly in anterior region, with short setae interspersed with sparse long setae; ventrite I about as long as ventrites II–III together; apex of ventrite V subrounded.

Measurements. Holotype, female, total length: 9.9 mm, prothorax length: 2.0 mm, prothorax width at widest point: 1.7 mm, elytral length: 6.8 mm, humeral width: 2.4 mm. Paratypes, male (n = 2)/female (n = 6): total length: 8.4–9.8/10.06 ± 1.10 mm, prothorax length: 1.8–2.1/2.08 ± 0.20 mm, prothorax width at widest point: 1.7–1.9/1.92 ± 0.23 mm, elytral length: 5.7–6.6/7.05 ± 0.73 mm, humeral width: 2.0–2.5/2.53 ± 0.25 mm.

Males. Ventrite V is more transverse and the apex is truncate (versus subrounded in female). Etymology

The specific name is in honour of Erika Valentina Vergara-Navarro (CTNI) for her kindness and help in providing access to CTNI and UNAB specimens needed for this and many other studies.

Remarks

Hemilissa erikae differs from other species of the genus by the following set of characters: pronotum without tubercles, disc with a longitudinal sulcus; elytra microsculptured on anterior half, remainder shiny; punctures on base of elytra not tuberculiform; elytral apices bispinose, with spines equal in size, and shorter than pedicel. See remarks in H. bifasciata .
